Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, in particular to a sampling device for ecological slope management. Background Art

[0002] In ecological slope management projects, accurate soil sampling is crucial for subsequent analysis and the development of management plans. By testing slope soil composition, structure, fertility, and other indicators, we can scientifically assess slope stability and ecological conditions, providing a reliable basis for management measures such as vegetation restoration and soil erosion control. Currently, common soil sampling methods rely on manual excavation with simple tools or traditional sampling instruments. While these methods meet basic sampling requirements to a certain extent, they still leave much room for improvement.

[0003] Chinese patent publication number CN219121732U discloses a sampling device for sampling vegetation on steep slopes. The device includes a shell, and a tail transmission box and an end transmission box connected to the shell are respectively provided at both ends of the shell. The drive shaft is rotatably installed in the tail transmission box, and a turntable is provided at the end of the drive shaft. The tape measure shaft is rotatably installed in the end transmission box. A transmission rod is provided in the shell, and the transmission rod is rotatably installed on a support frame in the shell. Transmission bevel gears are provided at both ends of the transmission rod, and a driving bevel gear meshing with the transmission bevel gear is provided on the drive shaft. A driven bevel gear meshing with another set of transmission bevel gears is provided on the tape measure shaft. The side wall of the end transmission box is provided with a through hole for the free end of the tape measure to pass through.

[0004] Existing sampling devices for ecological slope management have many drawbacks in practical applications. First, it is difficult to effectively avoid sample contamination. During the sampling process, plant debris and insect remains around the sampling point cannot be processed. These debris mixed into the sample will affect the accuracy of the test results.

[0005] On the other hand, the sampling operation is not convenient and efficient enough. From pushing the sampling device into the soil layer, separating the sample to taking out the sample, the operation steps are cumbersome and time-consuming.

[0006] In addition, the sealing and preservation effect of the samples is poor. The existing sampling device cannot seal the collected samples well, which easily leads to the volatilization and loss of effective ingredients in the samples, affecting the reliability of subsequent detection and analysis.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] Example 1, as Figure 1 and Figure 2 As shown, a sampling device for ecological slope management includes a handle 1, an anti-slip sleeve 2 is symmetrically fixedly connected to the outer surface of the handle 1, a connecting column 3 is symmetrically fixedly connected to the lower part of the outer surface of the handle 1, two connecting columns 3 are commonly fixedly connected to a sampling connection structure 6 at one end away from the handle 1, a sampling structure 5 is provided on the inner surface of the sampling connection structure 6, and a pedal structure 4 fixedly connected to the sampling connection structure 6 is commonly provided on the outer surfaces of the two connecting columns 3; the sampling structure 5 includes a sampling barrel 52 arranged on the inner surface of the sampling connection structure 6, a top cover 51 is provided on the upper inner surface of the sampling barrel 52, and a bottom cover 53 is provided at the lower end of the sampling barrel 52.

[0038] Further, in order to realize the sampling structure 5 being sent into the soil to realize the sampling of the soil, refer to Figure 3The pedal structure 4 includes a slider 42 that is slidably connected to the outer surfaces of the two connecting columns 3, and the outer surface of the slider 42 is symmetrically fixedly connected to the pedal 41. The lower end of the slider 42 is fixedly connected to the connecting column 2 43 that is fixedly connected to the sampling connecting structure 6.

[0039] By stepping on the pedal 41, the slider 1 42 is driven to slide downward, and the connecting column 2 43 is used to transmit downward pressure to the sampling connecting structure 6, thereby driving the connecting assembly 64 to move downward. At the same time, if the sampling connecting structure 6 and the sampling structure 5 cannot be removed from the soil layer, the sampling connecting structure 6 can be stepped on to pull the pedal 41 upward to lift the top cover 51 out of the soil layer.

[0040] Further, in order to fix the sampling tube 52 and drive the sampling tube 52 to take soil, refer to Figure 3 The sampling connection structure 6 includes a shell 61 fixedly connected to the lower end of the anti-slip sleeve 2, a partition 62 fixedly connected to the upper inner surface of the shell 61, a connecting component 64 slidably connected to the inner surface of the shell 61, and a connecting column 43 passes through the shell 61 and the partition 62 and extends to the upper end of the connecting component 64 and is fixedly connected to the connecting component 64.

[0041] The outer shell 61 is connected to the connecting column 3 and is used for supporting during the soil excavation process. Furthermore, the partition 62 installed inside it is a structure for switching the locking and unlocking actions of the connecting component 64, and is used to provide an installation place for the air pump 63. The connecting component 64 is used to connect the sampling tube 52, and the sampling tube 52 is fastened and locked inside the connecting component 64, thereby driving the sampling tube 52 to follow the action of the connecting column 2 43 to achieve up and down movement.

[0042] During operation of this embodiment, the sampling tube 52 with the top cover 51 engaged is first installed in the sampling connection structure 6. The handle 1 is held by the anti-slip sleeve 2, and the sampling connection structure 6 is aligned with the sampling point so that the bottom of the sampling connection structure 6 contacts the soil to be sampled. The sampling connection structure 6 cooperates with the sampling structure 5 to process vegetation, insects or other debris around the sampling tube 52, thereby preventing broken insect remains or leaves in the sample from contaminating the sample and the final test results. The pedal 41 is then stepped on to cause the slider 1 42 and the connecting column 2 43 to descend, driving the connecting assembly 64 downward to push the sampling tube 52 into the soil layer to be sampled. The sampling connection structure 6 is twisted by the handle 1 to separate the soil sample in the sampling tube 52 from the soil layer, thereby separating the sampling tube 52 carrying the sample from the soil layer. The connection assembly 64 cooperates with the sampling tube 52 to achieve rapid disassembly. The sample is further sealed by the cooperation of the bottom cover 53 and the sampling tube 52, thereby reducing the loss of effective components in the sample.

[0043] Example 2: Based on Example 1, this example uses the top cover 51 provided on the upper side of the sampling tube 52 in conjunction with the connecting assembly 64 to continuously provide airflow to the connecting tube 2 522 using the connecting tube 1 512, and utilizes the function of the Y-shaped tube 523 to cause the airflow to be diverted and then transported to the inner and outer surfaces of the sampling tube 52 respectively. By blowing on the surface of the slope soil, the weeds or insect debris around the sampling point are separated from the sampling area, thereby avoiding sample contamination caused by breaking leaves or killing insects during the sampling process and affecting the final detection results.

[0044] Specifically, in order to achieve the sealing of the sampling tube 52 and to cooperate with the bottom cover 53 to completely remove the sample after transporting it to the detection structure, refer to Figure 4 The upper end of the top cover 51 is provided with a plurality of tapered grooves 513 distributed in an annular manner corresponding to the positions of the tapered connectors 6443. The bottom walls of the inner surfaces of the plurality of tapered grooves 513 are provided with connecting pipes 512 connected to the side walls of the top cover 51. The upper end of the top cover 51 is symmetrically provided with notches 511, and the outer surface of the top cover 51 is buckled with the inner wall of the sampling tube 52 through a buckling groove.

[0045] It should be noted that a magnetic sheet is attached to the upper end of the top cover 51 , and when the top cover 51 is inside the connecting component 64 , it will be adsorbed together with the connecting component 64 .

[0046] The notch 511 on the top cover 51 is used to pinch and rotate the top cover 51 to separate it from the sampling tube 52. The connection between the top cover 51 and the sampling tube 52 is a conventional rotary buckle design, which is used to seal the inner cavity of the sampling tube 52. At the same time, a vent is provided on the top of the top cover 51 to exhaust air during the sampling process to prevent the internal air pressure of the top cover 51 from being too high.

[0047] At the same time, the conical groove 513 provided above the top cover 51 is docked with the slider 2 644, which can realize the continuous air supply to the sampling tube 52, thereby realizing the boundary between the weeds or insect debris around the sampling point and the sampling area, and then realizing the control of the sampling precision and sample accuracy, avoiding the contamination of the sample caused by the crushing of leaves or the killing of insects during the sampling process and affecting the final detection results.

[0048] Furthermore, in order to achieve the demarcation of weeds or insect debris around the sampling point, refer to Figure 4The upper part of the outer surface of the sampling cylinder 52 is provided with an annular groove 521 that is compatible with the slider three 6433. The lower end of the sampling cylinder 52 is fixedly connected with a number of teeth 524 distributed in an annular manner. The inner cavity of the sampling cylinder 52 is provided with a number of connecting pipes 522 distributed in an annular manner. The lower ends of the several connecting pipes 522 are provided with Y-shaped pipes 523 that are connected with the inner and outer surfaces of the annular groove 521. The inner surfaces of the output ports on both sides of the Y-shaped pipes 523 are fixedly installed with one-way valves 525. When the top cover 51 is on the inner surface of the sampling cylinder 52, the connecting pipe 2 522 is connected with the connecting pipe 1 512, and the lower end of the sampling cylinder 52 is tightly attached to the upper end of the bottom cover 53.

[0049] The annular groove 521 is used to cooperate with the connecting component 64 to lock and release the sampling tube 52. The connecting tube 2 522 opened in the inner cavity of the sampling tube 52 is connected to the connecting tube 1 512. The air flow is transported to the annular groove 521 through the connecting tube 1 512 and distributed to the inner and outer surfaces of the sampling tube 52 through the Y-shaped tube 523. At this time, the air flow can blow away weeds, leaves, and insect debris before the teeth 524 come into contact with the ground, so that a boundary appears between the sampling position and other positions, thereby ensuring the sample accuracy and reducing detection errors.

[0050] Embodiment 3: Based on embodiment 2, this embodiment further locks and releases the sampling tube 52 during the sampling process through the cooperation of the connecting component 64 and the partition 62 arranged inside the shell 61, and further locks the annular groove 521 in the sampling tube 52 during the sampling process through the action of the movable plate 642 and the locking piece 643 in cooperation with the slider 2 644, thereby driving the annular groove 521 and the slider 2 644 to move downward synchronously under the action of the connecting column 2 43 to sample the slope soil layer; at the same time, through the cooperation of the locking piece 643 and the upper partition 62, after the connecting component 64 is completely reset, the slider 3 6433 is prompted to leave the inner surface of the annular groove 521, thereby canceling the lock on the sampling tube 52, making it convenient for the operator to remove the sampling tube 52 from the connecting component 64, thereby improving convenience and practicality.

[0051] Specifically, to achieve the locking and unlocking of the sampling cylinder 52, refer to Figure 5 and Figure 6 The connecting assembly 64 includes a movable plate 642 fixedly connected to the lower end of the connecting column 43. The upper end of the movable plate 642 and the lower end of the partition 62 are fixedly connected with a tension spring 641. The lower part of the movable plate 642 is provided with a slider 644 slidingly connected to the inner surface of the outer shell 61. A plurality of locking pieces 643 are arranged in a ring shape on the upper end of the slider 644 and on its inner surface. The sampling tube 52 is arranged on the inner surface of the slider 644. The upper end of the top cover 51 is in close contact with the top wall of the inner surface of the slider 644.

[0052] The magnetic patch on the upper side of the top cover 51 can be adsorbed together with the top wall of the inner surface of the slider 2 644. The adsorption force of the magnetic patch can keep the connecting component 64 and the sampling tube 52 relatively stable regardless of whether the sampling tube 52 is empty or fully loaded.

[0053] When sampling is required, the second slider 644 is locked with the annular groove 521 by the action of the locking member 643, thereby preventing the sampling tube 52 from being separated from the second slider 644 during the downward or upward movement of the sampling tube 52;

[0054] When the slider 2 644 is reset to the uppermost position, the locking member 643 is reset. At this time, the slider 2 644 and the sampling tube 52 are only adsorbed together by the magnetic patch. At this time, the sampling tube 52 is sealed by the bottom cover 53, and the sampling tube 52 is taken out of the slider 2 644 and placed in a new sampling structure 5 to perform sampling again, thereby realizing continuous operation.

[0055] Further, in order to realize the locking and releasing of the annular groove 521, refer to Figure 7 and Figure 8 The locking member 643 includes a connecting rod 6434 fixedly connected to the upper end of the slider 2 644, the upper end of the connecting rod 6434 passes through the lower end of the movable plate 642 and extends to the upper end of the movable plate 642, the outer surface of the connecting rod 6434 is symmetrically fixedly connected to the limit block 6435 along the movable plate 642, the upper ends of the two limit blocks 6435 are each provided with a cross groove 6430, the inner surfaces of the two cross grooves 6430 are slidably connected to the cross block 6436, the two cross blocks 6436 are fixedly connected by a cylinder, the lower end of the connecting rod 6434 is provided with a hydraulic chamber 1 6437, the inner surface of the hydraulic chamber 1 6437 is slidably connected to the piston rod 6439 fixedly connected to the lower end of the lower cross block 6436, the depth of the cross groove 6430 is twice that of the cross block 6436, and the cross block 6436 located at the upper part is a magnetic block.

[0056] The locking member 643 also includes a hydraulic chamber 2 6438 opened at the upper end of the slider 2 644 and connected to a number of hydraulic chambers 1 6437. The inner surface of the slider 2 644 is provided with a number of sliding grooves 6432 distributed in an annular manner. The inner surfaces of the several sliding grooves 6432 are all slidably connected to the slider 3 6433. The bottom wall of the inner surface of the hydraulic chamber 2 6438 is provided with a number of connecting pipes 3 6431 distributed in an annular manner and connected to adjacent sliding grooves 6432.

[0057] When the movable plate 642 moves downward under the action of the second connecting column 43, the lower cross block 6436 will be pressed into the corresponding cross groove 6430. At the same time, the upper cross block 6436 will enter the lower half of the upper cross groove 6430. At this time, the piston rod 6439 moves downward and presses the hydraulic oil in the hydraulic chamber 1 6437 into the connecting pipe 3 6431 through the relay of the hydraulic chamber 2 6438. Then, it is transported to the slide groove 6432 through the connecting pipe 3 6431. The hydraulic oil expanded in the slide groove 6432 pushes the slide block 3 6433 toward the sampling cylinder 52 and enters the annular groove 521. At this time, the sampling cylinder 52 is locked relative to the slide block 2 644 through the action of the annular groove 521 and the slide block 3 6433.

[0058] During the reset process of the sampling tube 52 driven by the second slider 644, the third slider 6433 is only subjected to a longitudinal force and will not actively retract into the slide groove 6432, thereby ensuring that the second slider 644 and the sampling tube 52 are relatively locked during the reset process.

[0059] Furthermore, when the slider 2 644 is fully reset, since the movable plate 642 drives the upper limit block 6435 to rise during the reset process, the bottom cross block 6436 is not limited. When the slider 2 644 is reset, the upper cross block 6436 will be pulled closer to the partition 62 due to the magnetic effect and adsorbed together. At this time, the bottom cross block 6436 will be pulled upward synchronously, thereby prompting the hydraulic oil in the hydraulic chamber 2 6438 to be drawn back into the hydraulic chamber 1 6437 by the piston rod 6439. At this time, due to the volume change, the hydraulic oil in the slide groove 6432 will flow back into the hydraulic chamber 2 6438, and prompt the slider 3 6433 to retract and separate from the annular groove 521.

[0060] For further implementation, see Figure 9 The upper end of the partition 62 is fixedly connected to the air pump 63, and the output end of the air pump 63 is fixedly connected to the air pipe 1 645. The inner cavity of the slider 2 644 is provided with an air uniforming pipe 6441 connected to the air pipe 1 645. The inner surface of the air uniforming pipe 6441 is provided with a plurality of air pipes 2 6442 distributed in an annular manner. The top wall of the inner surface of the slider 2 644 is fixedly provided with a plurality of conical connectors 6443 connected to the air pipe 2 6442 distributed in an annular manner.

[0061] It should be noted that the above-mentioned air pump 63 is a conventional air supply device. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of providing air flow to the top cover 51 and the sampling tube 52 through the air pipe 645. Its internal structure, operating principle, wiring, and control method will not be described in detail.

[0062] The conical connector 6443 is adapted to the conical groove 513. When the sampling tube 52 is placed in the slider 2 644, the conical groove 513 is docked and connected with the conical connector 6443. At this time, the air path is the air pump 63, air pipe 1 645, air uniforming pipe 6441, air pipe 2 6442, connecting pipe 1 512, annular groove 521, Y-shaped pipe 523 and discharged through the one-way valve 525.

[0063] Embodiment 4: Based on embodiment 3, this embodiment utilizes the connection groove 534 opened on the bottom cover 53 to cooperate with the teeth 524 to receive the teeth 524 into the connection groove 534, and the rubber pad 535 squeezes and frictions the teeth 524 to cause the bottom cover 53 and the sampling tube 52 to be buckled together, thereby achieving sealing of the sampling tube 52 and the sample inside it; further, after reaching the detection structure, the top cover 51 is opened through the notch 511 and the cylindrical rod is inserted from the through hole 532 and pushes the piston block 531 upward, and the piston block 531 is used to completely push the sample out of the sampling tube 52, thereby improving convenience.

[0064] Specifically, to achieve the sealing of the sample and facilitate the removal of the sample, refer to Figure 10 The bottom wall of the inner surface of the bottom cover 53 is provided with a through hole 532 connected to its lower end. The bottom wall of the inner surface of the sampling tube 52 is fixedly connected to a tension spring 533. The upper end of the tension spring 533 is fixedly connected to a piston block 531 which is slidably connected to the inner surface of the bottom cover 53. The upper end of the bottom cover 53 is provided with a connecting groove 534 which is adapted to the teeth 524. The arc surfaces on both sides of the connecting groove 534 are fixedly connected to rubber pads 535.

[0065] The rubber pads 535 are elastic and have high friction. When the teeth 524 enter between the rubber pads 535, they are squeezed and frictionally held in the connection grooves 534, achieving a temporary seal.

[0066] The through hole 532 at the bottom can be inserted with an auxiliary rod with a predetermined diameter or less. When the upper cover 51 is opened, the auxiliary rod pushes the piston block 531 upward, thereby pushing the slope soil sample inside the sampling tube 52 upward, thereby achieving complete removal of the soil sample without manual detent or direct contact with the operator, reducing the impact of the effective components in the corresponding sample and improving detection accuracy.
